Componentes produtivos e produtividade de grãos de milho em função de densidades de Crotalaria spectabilis semeadas em consórcio

Abstract

The versatility of the consortium between grain and legume crops can meet the different characteristics of producers. However, the success of this consortium should be based on technical criteria, avoiding that green manure competes with maize and its management provides an increase in the production of straw for the no-tillage system without interference in maize productivity. The objective of the present work was to evaluate the productive components and productivity of second crop maize as a function of densities of Crotalaria spectabilis sown in a consortium. The experimental design was a randomized complete block design with four replications and four treatments, consisting of the isolated corn crop (Zea mays L.), as well as the maize consortium with Crotalaria spectabilis at four seeding densities (10, 20, 30 e 40 kg ha-1). It is possible to conclude that the consortium of second crop corn with Crotalaria spectabilis did not reduce the productivity of the main crop and that seeding densities of up to 15 final plants per square meter are recommended for the consortium.
